MEANS FOR COOLING INTERNAL-COMBUSTION ENGINES.

Application filed March 18, 1927. Serial No. 176,311.

5 ical in construction; and, more particularly,

to provide suchmeans which may be adjustable and for the purpose hereinafter explained.

This objectis attained by, and the inven- 10 tion finds preferable embodiment in, the

structure and mechanism hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which Figure 1 is a side view of an automobiles internal-combustion engine to which my cooling means is applied, the casing of the engine being partially broken away;

comprising each of these three series increase in length successively toward the outlet end 8 of the air passage, and are swingably mounted at 13 on the casing.

Means are provided for swinging these airdeflectors toward and away from the engine so as to contract or expand said passage, such means serving to hold the airdeflectors in the position to which they are thus swung. In the construction shown, such means comprises a link 14 pivotally connected at 15 to a plurality of the airdeflectors comprising such system, the link being movable to swing the air-deflectors by suitable means, such. as the screw 16 threaded in the casing and having a contracted shank portion 17 extending through a longitudinal slot 18 in the link, the head 19 of the screw serving to retain the shank por- Figure 2 is a top plan view of the same,

moved; and

Figure 3 is a detail view (enlarged) of a portion of the means for moving the air-deflectors to a desired adjusted position.

In the embodiment of the invention illustrated by the said drawings, an automobiles internal-combustion engine, designated generally 1, is shown comprising six cylinders 52 disposed in the longitudinal direction of A casing, designated generally 3, encloses this engine and comprises a lower member 4 and an upper or cap menu her 5 removably engaging the said lower member. This casing is spaced laterally from the engine (i. e., from its top and from its right-hand and left-hand sides) so as to provide an air passage extending between the engine and the casing from an inlet 6 at the engines forward end 7 to an outlet 8 at the rear end 9 of the engine. The forward movement of the traveling automobile drives the air rearwardly through this passage; or, particularly when the automobile is not traveling, air is forced through said passage by the usual fan 10 rotated by the engine shaft 22 and the belt 11. A plurality of air-deflectors are mounted in said passage extending in series in the longitudinal direction of the engine and automobile, such deflectors 12 being carried by the cap portion 5 above the cylinders, and the airdeflectors 12 being carried by the casings lower member 4 at the engines right-hand side, and the deflectors 12 being carried by said lower portion of the casing at the lefthand side of the engine. The deflectors ually turned by its knob portion 20 extending outside the casing, so as to move the link and the air-deflectors with it toward and away from the engine for the purpose set forth. An air-deflector 21 between the fan 10 and the front end of the engine, concentric with the axis of the fans rotation and cross-sectionally enlarging rearwardly, may be provided to drive the air toward the casing and the air-deflectors mounted thereon.

The invention being intended to be pointed out in the claims, is not to be limited to or by details ofconstruction of the particu lar embodiment thereof illustrated by the drawings or hereinbefore described.

I claim:

1. In an organization of the character described: an internal-combustion engine comprising a plurality of cylinders disposed in the longitudinal direction of said organization; a casing spaced laterally from the engine to provide an air-passage therebetween; a plurality of movable air-deflectors disposed in said direction in said passage and increasing in length successively toward its discharge end; means for moving the deflectors together and for holding the same in adjusted positionsrelatively to the engine to contract or expand said passage.

2. In an organization of the character described; an internal-combustion engine comprising a plurality of cylinders disposed in the longitudinal direction of said organization; a casing spaced laterally from the engine to provide an air-passage therebetween; a plurality of swingably-mounted deflectors therewith to adjusted positions deflectors disposed in said direction in said relatively to the engine. passage; a link connecting the deflectors to In testimony whereof I have hereunto set 10 swing the same together toward and away my hand at Grand Rapids, Michigan, this 5 from the engine to contract or expand said 15th day of March, 1927.
